** Y Plus Calculation**

- Y Plus calculation is important to correct wall heat fluxes for momentum and heat transfer
- CFD engineers should check Y plus to decide first element adjacent to wall in such a way that, y+ < 1

- The Y-plus calculation is given, you can enter your values in the column of input values

# Calculation of Pressure Drop

Based on flow resistances and flow rate, the pressure drop is calculated. Refer to the website for
